   It is imperative to note that all these realizations utilize the identical ellipsoid parameters ($a$ and $f$). The differences lie solely in the transformation parameters that map coordinates from the instantaneous physical surface (the realization) back to the fixed, idealized [ellipsoid model](/entries/ellipsoid-m…
